This laser generates IR light with the wavelength of 5mm.

This is not always possible because two similarly coloured objects can have completely different reactions to near IR light.

Red goggles, for example, will block most green light from entering the eyes, but will pass IR light.

These diode-based visible lasers do not produce IR light.

Ding tipped his goggles up to expose the IR light and blinked it three times.

When IR light of these frequencies strikes an object, the energy is either reflected or transmitted.

The IR light is directed through the sample chamber towards the detector.

This IR lights allow the active glasses to sync with the display and create a 3D image.

You see IR lights keeping food warm in restaurants.

It also has additional protection on IR driving lights.
